This may be a stupid question but can I have my battery connected to the car and hooked up to a tendor during the winter? Had a little trouble after winter storage with emissions since all my system reset since my battery was disconnected.

Yes, I have done this numerous times over the winters. Just make sure it's a "smart" tender (although most are now these days?). I've primarily used the Deltran, never had any issues with my Camaros or motorcycles. If you start the car every so often, disconnect the tender first.

Cool thanks. I have the one that is suppose to shut off when the battery is fully charged. I say supposed cause never actually saw it happen but good info to know thanks again.

It said it was a Deltran battery tender on an AC Delco Freedom Battery.

Oh boy, that's not good. Any other info? Age & condition of the battery? Was there a power surge? Was an extension cord used, if so how long was it & was it heavy duty? I'm no expert, but there are too many other factors possibly affecting this.

I use a Deltran Battery Tender Jr on the OEM original battery. It is permanently connected using the ring lugs. When it is plugged in, I keep the plug module outside the car and it is plugged into a heavy gauge extension cord. I also do not latch the trunk when it is plugged in. So far, it's worked as advertised with no problems.

I have used the Deltran tenders for about 6 years, and I've had no battery run downs or problems since. This is a first for me hearing about a catastrophe with one of them. Mine is left on 24-7 as well.
